Last week’s G8 and G20 meetings in Toronto and its environs confirmed that the world’s leaders accept the demise of global-warming alarmism.
One year ago, the G8 talked tough about cutting global temperatures by two degrees. In Toronto, they neutered that tough talk, replacing it with a nebulous commitment to do their best on climate change — and not to try to outdo each other. The global-warming commitments of the G20 — which now carries more clout than the G8 — went from nebulous to non-existent: The G20’s draft promise going into the meetings of investing in green technologies faded into a mere commitment to “a green economy and to sustainable global growth.”
These leaders’ collective decisions in Toronto reflect their individual experiences at home, and a desire to avoid the fate that met their true-believing colleagues, all of whom have been hurt by the economic and political consequences of their global-warming advocacy.
Kevin Rudd, Australia’s gung-ho global-warming prime minister, lost his job the day before he was set to fly to the G20 meetings; just months earlier Australia’s conservative opposition leader, also gung-go on global warming, lost his job in an anti-global-warming backbencher revolt. The U.K.’s gung-ho global-warming leader during last year’s G8 and G20 meetings, Gordon Brown, likewise lost his job.
